most dogs will not bond with chickens, even good livestock guardian dogs. Many dogs will accept chickens and not bother them though. Many, many different breeds of dogs work for this. It really depends on the dog's personality and how good a job you do training it.

I've had good results with my GP's. they guard all my chickens and exotic fowl. They let the geese & swan bite them with out retaliation, let the cranes pounce on them why they are sleeping and share their food with the chickens..... however not all Gp's are good with birds, as with most breeds their are those better than others. Many dogs w/o a huge prey dog can be taught to be good around birds, it depends on temperament and how much time you put into training them.

Last night Bear our Bernese Mountain dog chased of a raccoon. (He is even more aware than our previous dog, a Golden. He watches TV even with the sound off he will growl at a wild animal on the tube.) My chickens even walk under him through his legs and he very careful not to move until they are clear.

My Anatolian Shepherd, Dakota, is great with my birds we have a large red fox population where we live, and they don't dare visit my flock when Kota is around they share scraps with him sometimes. He makes my big RIRs look like bantams though! no wonder, he's 140 pounds!
